'A shaft I9 is secured; tqithe, table top I2 and slidably""ari'd rotatablymountedi in the hollow post 18 y "The-"table tiop IZ-may' be. ofanydesired conjtour-cirdhlanorsquare asher'ein' shown; or oval. *It may be constructed 'in the conveiitirronal manner,-'preferably rifith a ri'm 20 j'depending" from the perimeter of "the {to'p I 2 arid 'thereby "forming 'a cavity: I on-the underside'bfthe" top. "'A s'ubtop '22 coextensiveflwith"the table' top I2' is se- "ciir'd t the uriaerraee tr the rim 2 0- so; as"--'to inclose the cavity 2I to provide a chambers-mere- --'in tl'ieupper portion of the cam-track" followers 'I5 -are-housed. F'I'he subtop Tit-may -be-"-bf i any suitable mat'erial such -as plywo'od" or=' r'e'sse'd fib're board. 'The cam tracks 1 I 6 *are' cut' -in 'tlie "subtop 22, extendin spira11 outward from a 'pbiiit"nean-the center' in theform bf arcsf-td'a point near the perimeter (see Fig. 5).

The leg extensions I4 are each provided with mount brackets 23 and 24 oppositely curved and located at the opposite ends of the extensions and hinged to the legs I 3 and the cam-track followers l5 by pivot pins 25 and 26 respectively.

Each leg extension I4, and the companion leg I3 are cut away at 21 and 28 (see Fig. 9) to provide a recess for a tension spring 29 embracing hinge pin 25. The ends of spring 29 bear against the extension I4 and the leg I3 so as to normally urge the extension I4 toward its elevated or extended position, as shown in Figs. 4 and 7. It should be observed that the vertical axis of the pivot pins 25-2B are not in alignment with the vertical axis of the leg extension I4. (See Fig. 7).

The cam-track followers l5, as herein shown, each comprises a pair of blocks 30 and SI secured together on opposite sides of the subtop 22 by a screw pin 32 which extends through the cam-track slots I 6.

A table embodying this invention is designed for use generally as a cocktail, cofiee, or occasiona table in front of a living room davenport orlounge. When so used the top l2 would be disposed at -its lower level,- resting on the upper ends of legs l3 with the extensions folded inwardly and horizontally under the top I 2 (see Figs. 2 and 8). So arranged, the top I2 is too low' to be used for instance, as a card table. However, the table top [2 may be convenientlyv and easily shifted to a higher level so as to make the table available for such use.

perimeter of the table top I 2 at two points and giving the table top [2 a rotative movement in a clockwise direction, as it is lifted." 'This'move- "'ment of the tabletop relative to the base I I will cause the pins 32 in'the cam-trackfollowers [5 to follow the cam-track grooves l6 in'a lateral direction thereby allowing the springs 29 to urge the leg extensions M to the vertical positions shown in Figs. 4 and 7.

When it is desired to reconvert the table to its normal use it is only necessary to reverse the rotation of the top I2 and press downwardly that is, rotate the top in a counterclockwisedirection so as to cause the cam-track follower pins 32 1 in the cam-track groove l6 to move inwardly to- .wards the center of the table. This will effect a swing of the leg extensions l 4 inwardly and down- .wardly against the action of the springs 29 allowing the top to come to rest at its lower level on the legs 12, as shown in Figs. 1 and 6.

Other variations and modifications in the details of structure and arrangement of the parts may be resorted to within the spirit and the cov- .erage of the following claims: c

I claim: 1. A table of the class described comprising a 2. A table of the class describedcomprising a supporting base, a top rotatably mounted on said base, arcuate-shaped, substantially spirally extending cam tracks, a plurality of links hinged to said base and to said followers for shifting between horizontal and vertical positions whereby This c'onversion is easily efiected by a person grasping the.

"base.

4 rotative movement of said top disposes the same at vertically different levels, and means yieldingly urging said links into their vertical positions.

3. A table of the class described comprising a supporting base mounting a plurality of spaced vertical legs and a central post, a top mounted for axially shifting on said post, substantially spirally extending cam tracks formed on the under face of. said top,,,.camtrack,followers slidable on said tracks, link extensions hinged one to each of said legs and to one of said followers whereby said top may be disposed at vertically different levels with respect to said base, and yielding means for holding said top in the upper of said levels.

4. A table of the class described comprising a supporting base'mounting a plurality of spaced vertical legs and a central post, a top rotatably mounted on said post,. a plurality of arcuateshaped substantially spirally extending cam tracks formed onthe under face of said top, and link extensions hinged oneto each of said legs and to one of said followers whereby'rotative movement of said top disposes the same at vertically difierent levels with respect to said 5; A table of the class described comprising a supporting base, a top formed with a perimetrical rim depending therefrom, a subtop substantially coextensive with said top secured to the under face of said rim and having substantially spirally extending cam grooves formed therein, blocks suspended from said subtop and each having 'a pin to traverse one of said grooves, and links hinged to said base and to said blocks whereby the shifting of said block pins in said grooves disposes said top at vertically different levels with EARL L.
